FEEDING MECHANISlVI FOR CARDlNG-MACl-IINES.

SPECIFICATION forming part of Letters Patent No. 534,418, dated February19, 1895.

Application filed February 11, 1893. Serial No. 461398. (No model.)

To all whom it may concern:

Be it known that I, EDDO V. BATES, a citizen of the United States,residing at Dracut, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful ImprovementinFeeding Mechanism for Oarding-Machines, of which the following is aspecification.

My invention relates to carding machinery and consists of devices andcombinations hereinafter described and claimed, and includes an improvedfeeding apparatus for feeding slivers positively.

In the accompanying drawings on five sheets, Figure 1 is a perspectiveview of a carding engine provided with my improvements. Fig. 2, is aplan of the feed aprons, feed-rolls, tumbler, feeding-head ordistributing carriage and actuating mechanism with parts of the frame;Fig. 3, a front elevation of the distributing carriage, a part of theframe on which it travels, a sprocket-chain which causes said carriageto traverse, and one of the side-belts; Fig. 4, a plan of what is shownin Fig. 3; Fig.5, a front elevation of a part of the frame on whichthedistributi-ng carriage travels at the right of the machine, sh owingthe gearing which drives the sprocketchain and rotatesthe shaft, bywhich the dis tributing rolls of the carriage are operated, showing alsoin front elevation one of the side-belts; Fig. 6, a plan of the partsshown in Fig. 5, omitting the side-belt; Fig. 7, arear view of the spurgears shown in Fig. 5, a part of the frame shown in Fig; 5, and therotary shaft supported therein; Fig. 8, a left-side elevation ofthedistributing carriage, its actuating gear and one of thefeed aprons,showing in section the carriage supporting-rail and the feed-table andthe carriage operating shaft and sprocket-chain; Fig. 9, a right-sideelevation of the carriage, omitting the stud on which the chain-engagingpin slides and' a cross section of the carriage-actuating shaft; Fig.10, a horizontal section on the line 10 10 in Fig. 9. Fig. 11 is acentral vertical fer-roll and the gears which connect said sideshaftand'the feed-rolls; Fig. 12, a plan of a part of the frame, a part of themain. cylinder audits shaft, the fast pulley and loose pulley on saidshaft and a plan of the mechanism which drives the feed-rolls and thelumper-roll from the shaft of the lower doffer; also a part of saidlast-named shaft; Fig. 13, a side elevation of the link of thesprocketchain which carries a pin to engage the slide on the carriage.and a vertical section of said slide inthe plane of the axis of saidpin.

In Figs. 1, 2, Hand 12, A denotes the frame of a breaker-card; B, themain cylinder; 0, the tumbler; D, the workers; D, the strippers; E,-theupper and E the lower doffer;

F, the rubbers or rub-rolls, between which the rovings pass from thedoifers to the spools G, the latter being rotated by a frictionalcontact of said spoolers or of the rovings wound around them, with thedrums H, these parts being all of the usual construction and operationas usedin wool-carding engines.

. The sliver-feeding devices hereinafter described are animprovement onthe so-called Apperly feed, said Apperly feed being shown and describedin United States Letters Patent No. 18;888,granted December 22, 1857, toJames Apperly and William Clissold.

The frame a, represented in Fig. 2, supporting apron-rolls 'i 2". (Figs.2 and 11), on which run, narrow feed-aprons I of card-clothing, thefeed-rolls N N and the side-belts K, are of the usual construction andoperation as-co'mmonly used in the so-called Apperly feed and aresubstantially as shown in said patent, except as hereinafter stated.Instead of the floor-delivery shown in said patent, an overhead deliveryis now oommonly'usod, as represented in Fig. 1, consisting of a groovedpulley L, journaled in a laterally swinging arm and weight. I drive thecarriage M by an endless chain M, running on the sprocket-wheels m m,the wheel in being fast on the same shaft 077. with the bevel-pinion msaid pinion m being engaged by another bevel-pinion in, fast on the sameshaft m with the spur-gear m said gear m being driven by a pinion mconcentric with and turning with the bandpulley m and said pulley mbeing connected by a belt m with a band-pulley on fast on the shaft ofthe upper rear feed-roll N hereiuafter described (see Figs. 2 to 6), onelink of the chain M having a pin m which enters a hole m in a slide mcapable of moving vertically on a stud m fixed in the top of saidcarriage. (See Fig. 13.) The shaft on is by the means above describedrotated at a uniform speed.

The guide-frame O is supported by vertical posts 0 on the frame a andconsists of a bottom-rail 0 (Figs. 2 to 8), shaped in crosssection likean inverted T and having at its ends stands 0 0 in which is journaled ashaft 0 which guides and supports said carriage M and also drivesdistribu ting-rolls m m hereinafter described.

The shelf 0 or rear part of the base of the rail 0 supports standards 00 in which the shafts 122 771 of the sprocket-wheels m m are journaled,and which are secured to said rail 0 by bolts 0 which pass through saidstandards and through slots 0 in the vertical web 0 of said rail, saidslots permitting the lateral adjustment of the standards when necessaryto tighten the chain M or to adjust the position of the gears on theshaft m to the gears by which they are engaged. The tension of saidchain M may also be varied by raising or lowering the idlesprocket-wheel m which turns loosely on a horizontal stud 0 rigidlysecured to a plate 0 which, by means of bolts 0 passing through avertical slot 0 in said plate into a standard 0 (substantially like thestandard 0 and supported in like manner therewith), may be held at anydesired height.

The carriage M (Figs. 3, 4, 8, 9, 10 and 13) consists of a verticalplate m having three backwardly-extending brackets m m m" rigidlysecured thereto,the uppermost bracket 171. surrounding the guide-shaft Oand having a sliding fit thereon. In the two lower brackets m m" isjournaled a vertical shaft m having fast thereon a spur-gear 972 and ina swinging frame 977. pivoted between the brackets m m", is j ourn aledanother vertical shaft m having fast thereon aspur-gear M caused toengage the gear 122 by a spring 001 secured to the plate m and pressingagainst said swinging frame (Figs. 8, 9 and 10). On the lower ends ofthe shafts m m are fast the fluted distributing-rolls m M which meshinto each other and pull the drawing L through a trumpet m of the usualconstruction, and deposit said drawing on the feedaprons I when saidshafts m on are rotated as hereinafter described.

The carriage M is prevented from swinging forward by a guide-wheel mwhich is fast on the shaft on and presses against the front side of thevertical part 0 of the rail 0 The shaft 'm has fast thereon at its upperend, a bevel-gear m which engages a bevel-gear 0 which turns with theshaft 0 and also has a longitudinal movement on said shaft with thecarriage M, said shaft having a key-seat 0 extending from end to endthereof, engaged by a spline secured in the hub of said beveled gear 0".

The shaftO'(Figs. 3 and 6) is rotated through a train of gears, asfollows: The gear 0, fast on the shaft on of the sprocket-wheel m, andengaging the intermediate gear 0 the latter engaging the gear 0 fast onthe shaft 0 and a bevel-gear 0 on said shaft 0 engaging a bevel-gear 0fast on said guide-shaft O.

The shaft m is rotated through connecting mechanism above described fromthe shaft of the lower rear feed-roll N An arm 0 (Figs. 5 and 7),capable of swinging on the shaft 0 is held in the desired position by abolt 0 which passes through a slot 0 curved concentrically with saidshaft 0 said arm having also a straight slot 0 radial to said shaft o,in whichslot the stud 0 ,on which said intermediate gear 0 turns, isadjustable in a well-known manner, so that either of the gears o 0 maybe changed for a gear of a greater or less number of teeth to vary thespeed of the distributing-rolls,and the amount of drawing depositedthereby on the feedaprons, the speed of the distributing rolls beingregulated according to the speed of the delivery of the drawing L. I

In said Patent No. 18,888 are represented two levers, sometimes calledlatches, around the free end of which alternately is laid the bightofthe drawing L, at the end of the traverse, to prevent the last deliveredcourse of the drawing being pulled out of place by the tension of thedrawing, each lever or latch being raised out of such engagement just before a new bight is formed. The rolls which in said Apperly feed, asheretofore used, most nearly correspond in position to mydistributingrolls are not distributing rolls or feedrolls, being placedtoo far apart to exert any holding pressure upon the drawing and servingmerely as guide-rolls or idle-rolls. The unequal contraction of thedifferent courses or parallel lines of the drawing on the feedapronscauses the edges of the lap formed by said lines of drawing to be unevenand the outer slivers formed from said lap to vary so greatly in weightand size in different parts that these outer slivers, one at each sideof the machine, are called waste slivers and are commonly returned tothe first breaker after passing between the rub-rolls, the rovingsformed from the waste slivers being too uneven to be spun. These latcheslam enabled to dispense with, partly because I use the positively drivendistributing-rolls m m which deliver the drawing uniformly atall timeswhen the carriage M is traversing in either direction, and partlybecause'I lengthen the side-belts K, causing them to extend forwardunder the guide-frame O, as near as possible without interference, tothe plane in which the rear faces of the distributing-rolls lie, so thatthe last-laid course of drawing will be caught between said side beltsand the feed -aprons before a new course is laid. It will be understoodthat these side-belts K are parallel endless belts of card-clothingrunning on idle pulleys 7c and on other pulleys it fast on the shaft 10the latter being provided with a fast gear 10 which engages a fast gear(not shown) on the shaft of the rear roll 01 of the feed-aprons I, inthe usual manner.

Heretofore it has been customary to use a single pair of card-clothedfeed-rolls N N to take the lap of drawing from the feed-aprons I andside-belts K (see Figs. 2 and 11), and deliver the same to leaders-in(not shown) or directly to the tumbler G, which in turn delivers thefibers to the main cylinder B. I arrange a second pair of feed-rolls NN, between said first pair and thetumbler, the cen ter of the roll N orlower roll of the second pair being at equal distances from the centersof the roll N N said second pair being precisely like the first pair,{but run at a higher rate of speed in order to draw the fibers andpresent them to the tumbler at right angles to the axis thereof, insteadof parallel therewith, in order that the fibers may be placed straighton the cylinder B and to prevent the outer slivers from a variation inweight and size due to the irregular bending of the drawingL' at thesides of the lap. The upper front feed-roll N has a gear at whichengages a precisely similar gear (not shown) on the shaft of the lowerfront feed-roll N in the usual manner, so that said front feed-rolls aredriven at the same surface speed.

The shaft of the lower front feed-roll N is provided with a spur gear'n'which engages a spur-pinion n secured to a bevel gear nconcentrically therewith, said bevel-gear a eugaging a bevel pinion afast on the front end of the side shaft 91 said side shaft having on itsrear end another bevel gear n which engages a bevel-pinion a fast on theshaft 6 of the lower doffer-roll E, said lower dofferroll being driventhrough a belt and gearing from the shaft 13 of the main cylinder B.

The shaft of the upper rear feed-roll N is provided with a spur-gear nwhich engages a precisely similar gear atom the shaft of the lower rearfeed-roll, so that both rear feedrolls have the same rate of speed (seeFigs. 2, 11 and 12) and the shaft of-the lower rear feed-roll isprovided with a band-pully n (Fig. 1) connected by a belt at with apulley b fast on the shaft of the main cylinder. The roll N takes thefiber from the rolls N N and carries it up to the roll N which alsocleans the fiber from the roll N.

The fibers are presented by the rear feedrolls to the tumbler O whichruns at a greater rate of speed than said rear feed roll which deliversthe fibers to the main cylinder B, as above stated, in the usual manner.In the angle below and between said tumbler and main cylinder I arrangea lumper-roll P, the same being covered with a card clothing androtating in the direction shown by the adjacent arrow in Fig. 11, beingdriven by a belt 10' which connects the band-pulley 19 fast on the shaftof said'lumper-roll with another band-pulley 19*, fast on the shaft e ofthe lower dofler-roll E.

The lumperroll does not entirely strip the tumblerG but evens the stockon said tumbler, catching the bunches and surplus stock on said tumblerand pulling the bunches apart, the-adjacent surfaces of said tumblerand. lumper revolving in opposite directions. The lumper-roll isstripped by the cylinder B.
